This invention" relates to carriers or spindles for'braiding machines,and the like, such as plaiting machines The object of the invention isan improved constructional form of carrier or spindle suitable for workat higher speeds than has hitherto been possible.

The invention is illustrated 1n the accoinpanying drawings in which rFig. 1 is a side elevation of one form of carrier made in accordancewith the invention. v V

Fig. 2 is a plan of Fig. 1.

Fig. 3 is a rear elevation of Fig. 1.;

Fig. 4 is a sectional plan on line 4 4 Fig. 1.

Figs. 5 and 6 aredetail views of a modified construction of eyelet forthe upper end of the back and other parts.

As illustrated, the base a of the carrier is a casting, the lower partof which is formed with an oval sliding surface 6, a depending guide web0, a retaining flange d and a driving peg 6. At the leading end of thebase is an upstanding column f in the top of which is fixed an uprightsteel rod g formingthe spindle for the bobbin holder. In the base ofvthe column f is a through slot in which is in at the time'of casting thebase, is a flat steel back Z, the edges or narrower sides of which arerounded. In the steel backand at a point upwards from its base abouttwothirds of its length is a split eyelet Z cut intothe back for quickyarn threading, the cut or split of the eyelet being inclined downwardlytowards the hole, the edges of which 5 arebevelled; Below the eyelet isa hole m which receives the end of a spring wire collar m wound tofit'closely on the back and pro-.

, viding a quickly fitted stop. On the back and below such stop arearranged in ordera stop plate or collar n of 'D shape, a light wire coilnut cut-(see Figs. 5 and 6).

spring 0, round or flat to conform with the shape of the back Z,-and asliding-weight p, the latter'having the usual hook p for the yarn g,'ancl-wings p I i At the upper end of the back -Z is a pigtail eyelet1', made entirely of wire, the eyelet end 7* projecting behind the back,the other part of-the wire being wound to fit closely to the back Z withthe extreme end r bent inwardly to fit into ahole in the back andthereby be positioned. On theback- Z isa" light coil spring 8, round,oval or rectangular as in the case of the yarntensioning spring 0, andforming a return spring for the catch it through a catch wiret, whichlies alongside the back, the upper end being bent to fit slidably on theback and to engage "the lower end of the light spring 8 and the otherend being hooked round the stud 7' of the catch counterweight.Intermediate of its lengththe wire t is doubled on. itself to'form alaterally projecting loop 25 'adaptedito be engaged by one of the wingsp of the tensioning weight 713.

Oval springs, such as s shown'inFigs. 5

and 6, may be used instead of round springs. The bobbin holder itself isformed with a long spindle constructed in known manner to hold thebobbin and is cast with a light cir= cular base u having downwardlyprojecting webs '0 to be'engaged by the catch 719, the hub of the basenormally bearing on the top of the column f already described.

The wire pig-tail eyelet at the top of the back may be replaced by asteel eyelet w threaded and screwed into the top of the steelrectangular back and locked in position by a f The operation of thecarrieras one of 'a known type and its movements in the braiding'machine will be well known and the manner in which the tensioning weightp is loop 25. of the catch wire tfrequently, to -release the bobbin'asmore yarn is required and always again releasing the catch h so that thebobbin is held and so that the re- 'quired tension may be maintained.Theimproved carrier has the. advantage that-the difliculty with thesecarriers.

it is less fragile and-by casting it in'witli the base part theadvantage of the rigidity of the ovalsection'back is retain-ed'withoutthe disadvantage which would result from the larger diameter of rod thatwould be required if round and having the same lateral rigidity,and alsothe cost offiXing the parts together is very small as wellas ensuringabsolute rigidity. Further, there are few parts to work loose which'isthe main The general construction'anid arrangement of the parts 4. Acarrier according to claim 2, characterized in that the said furtherstop at the upper end of the guide is made of wire coiled to fit closelyon the guide and having one end turned in to engage a hole in the guide,and the other end projecting and twisted to form a pig-tail threadeyelet, as set forth.

In testimony whereof I have signed my name tothis specification-BENCARTER.

is of importance in so far as security with ease and simplicity of theirattachment or replacement 18 obtained, but the inventionis not limitedto the particular details of the example above described as will beapparent from the. description itself.

Vhat I claim is r 1. A bobbin carrier for-braiding machines and thelike-having a. vertical guide, a thread eyelet in the guide oppositethe-bobbin, a

catch releasemember slidably mountedatits upper endon the guide abovethe said" thread eyelet, .anda thread tension. weight slidably mountedon the guide and adapted to engage the said catch release'member,characterized by a stop on the guide belowthe said thread eyelet, aspring'on the guide between the said stop and the thread tension weight,and a projection on the catch release-member intermediate'of its length,to beengaged by the said. weight, as set forth.

2. A carrier for braiding machines and the like having a vertical guide,a thread eyelet in the guide opposite thebobbin, a catch release memberslidably mounted. at its upper end on the guide above the said threadeyelet, and a thread tension weight slidably mounted on the guide andadapted to engage the said catch releasemember, characterized V by astop on the guide below the said thread eyelet, a spring onthe'guide-between the said stop and the thread tension weight, a projectionon the catch release member intermediate of its length to be engaged bythe said weight, a further stop at the upper end of the guide, and afurther spring on the guide betwcensaid further stop and the upper endof the catch release member, as set'forth.

0. A carrier according to claim 2, further characterized in that thesaid further stop at the upper: end of the guide also constitutes athread eyelet, as set forth.
